BACKGROUND

1. Field

The present disclosure relates to apparatus for providing contents.

2. Description of the Related Art

Advertising is to provide information about a specific commodity or service (hereinafter referred to as the “commodity”) to potential consumers and customers in order to promote the sales and distribution of the commodity, and corresponds to one-way communication.

Advertising media includes a variety of media such as wallpaper, a poster, a signboard, street facilities, a leaflet, radio, a movie, TV, a web banner, a popup advertisement, a magazine, a newspaper, a sticker, and a shopping cart.

However, such advertising media utilize still images, and therefore the amounts of information to be provided are limited. Although moving image information is utilized recently, it is difficult to repeatedly view and analyze the moving image information which is played.

Meanwhile, mobile terminals are communication devices which have the advantage of being able to wirelessly connect to a mobile communication system, and wirelessly connect to and communicate with desired counterparties anytime and anywhere while moving. Such mobile terminals are always carried because of the characteristic of communication that communication may be made anytime and anywhere, but have low utilization rate because the period for which they are actually utilized for communication is short.

Therefore, in order to increase the utilization rate of mobile terminals, additional functionalities, such as E-book, MP3, camera, recorder, scanner, multimedia player, and game machine functionalities, have been added to the mobile terminals. Recently, mobile phones to which tablet computer functionality has been added have been introduced under the name of smartphones. The development of mobile phones to which functionality is added tends to continue.

Furthermore, short-distance wireless communication functionality, such as Bluetooth, Radio Frequency Identification (RFID), and/or Near Field Communication (NFC), is added to mobile terminals, and therefore the mobile phones can perform tag functionality for managing the history information of commodities, smartcard functionality for performing electronic payment, and/or Peer-to-Peer (P2P) functionality for performing one-to-one communication.

Conventional advertising media have the disadvantages of instantaneously providing information, and being unable to review the content of an advertisement when a person moves away from a location where the advertisement is made. Conventional moving image-based advertising media also have the disadvantages of being unable to review the content of an advertisement over time, being unable to represent information using a moving image at times, and being unable to review the content of an advertisement when a person moves away from a location where the advertisement is made.

That is, conventional advertising media is disadvantageous in that it is difficult to review the content of an advertisement when a person moves away from a location where the advertisement is made, a still image advertisement can represent a relatively limited amount of information, and a moving image advertisement cannot represent information which needs to be reviewed and analyzed for a long time, such as a railway schedule.

Therefore, there is a need for a technology which receives the content of an advertisement from an advertisement medium, records the advertisement in a mobile terminal, and allows a user to repeatedly review and analyze the content of the advertisement when the user moves away from the advertising medium and needs to repeatedly review and analyze the content of the advertisement for a long time.

Mobile terminals are communication devices which are capable of wirelessly connecting to and communicating with desired counterparties anytime and anywhere while moving within service areas. Such mobile terminals which are always carried to prepare for communication that may be made anytime and anywhere have low utilization rate because the period for which they are actually utilized for communication is short. The utilization rate of mobile terminals tends to be increased by adding additional functionalities, such as E-book, MP3, camera, recorder, scanner, multimedia player, and game machine functionalities, to the mobile terminals Recently, the utilization rate of mobile terminals is further increased by adding NFC functionality for performing tag functionality, smartcard functionality and P2P functionality.

Since current mobile terminals tend to be equipped with NFC functionality, a mobile terminal will be described as being an NFC mobile terminal in the following description.

Furthermore, thanks to the development of communication technology, the development of manufacturing technology and the improvement of mass production technology, the price of NFC mobile terminals and the communication cost have been reduced, and each adult has about one NFC mobile terminal with the advent of the personal communication era.

Meanwhile, a purchaser who purchases a commodity has prior knowledge about the corresponding commodity and purchase the commodity selected at need, while a vendor generally perform the promotion or advertising of his or her commodity so that the commodity can be selected by many purchasers.

Purchasers may hesitate or may not immediately make up his or her mind when there is a plurality of commodities of the same type or a similar type.

A barcode or a Quick Response (QR) code indicative of information, such as the name, manufacturer, price, release date, expiration date, serial number and location of a commodity, is represented on a commodity.

Conventionally, information about a commodity, such as the advertisement, use and functionality of the commodity, is provided using advertising leaflets, specifications and promotion materials in the form of a discontinuous and concentrated event.

Therefore, it is difficult for a user or a purchaser to obtain the advertisement information of a commodity in such an event where the commodity is advertised. Furthermore, even when a person participates in such an event and becomes aware of the advertisement information of a commodity, the person forgets the information over time, and therefore the effect of such advertising is very low.

Furthermore, since specific information about a commodity, such as the advertisement information, expiration date and use of the commodity, is frequently changed and updated, it is difficult to provide accurate information to purchasers.

Therefore, there is a need for the development of a technology which is capable of providing information about each commodity (hereinafter referred to as “commodity information”) including, for example, the advertisement infolination, promotion information, name, release date, expiration date, manufacturer, serial number and price information of the commodity using a QR code or a barcode (hereinafter referred to as an “optical code”) which is represented on the commodity.

In particular, there is a need for the development of a technology which is capable of providing commodity information, included in an optical code represented on each commodity, to an NFC mobile terminal which is being carried by an individual person using NFC communication, so that a purchaser can rapidly check accurate commodity information.

The foregoing discussions are only to provide background information and do not constitute an admission of prior art.

DESCRIPTION OF EMBODIMENTS

Reference now should be made to the drawings, in which the same reference numerals are used throughout the different drawings to designate the same or similar components.

Some embodiments will be illustrated in the accompanying drawings and described in detail below. However, it should be appreciated that this is not intended to limit the present invention to the specific embodiments, but the present invention includes all modifications, equivalents and alternatives which fall within the spirit and technical range of the present invention. Descriptions of well-known functions and constructions which have been deemed to make the gist of the present invention unnecessarily vague will be omitted below.

In embodiments of the present invention, an advertisement medium is described as being a multimedia signal including an image(s), a character(s), and a sound signal, and an operation applet is described as being an application program which performs control for a selected application.

That is, a mobile terminal includes a plurality of application programs, each of the application programs is referred to as an operation applet, and the application programs are identified by respective pieces of applet identifier (AID) information. Furthermore, the same applets may be assigned different pieces of applet identifier (AID) information when their versions or manufacturers are different.

When a mobile terminal communicates with a counterparty mobile terminal, or a mobile terminal operates a specific application program in conjunction with a counterparty mobile terminal in a one-to-one correspondence, they should include and operate the same applets having the same applet identifier (AID) information.

Communication mode in which signals are transmitted and received in NFC communication includes card mode and read mode. The card mode is described as being mode in which recorded information signals are provided to a counterparty, and the read mode is described as being mode in which the recorded information signals of a counterparty are read.

A barcode is a linear one-dimensional (1D) code which is formed by combining a plurality of white and black bars having different widths and can be easily read by a computer, and is widely used to represent the unique number and/or price information of a commodity.

A Quick Response (QR) code is a matrix-type two-dimensional (2D) code which is formed by arranging small square dots equally in lateral and vertical directions and can be read by a computer. A QR code may have on its each side dots the number of which ranges from 21 to 177, can record a maximum of 23,648 bits, can be recovered thanks to its supplementary property when part of its data is damaged, and can be recognized or read in all directions of 360 degrees.

Tagging or tag is described as a state of being close to a counterpart with or without physical contact.

FIG. 1 is a functional block diagram illustrating the configuration of an advertisement information provision system 10000 according to an embodiment of the present invention.

Referring to FIG. 1, the advertisement information provision system 10000 according to the embodiment of the present invention will now be described in detail. The advertisement information provision system 10000 includes a mobile terminal 11000, a panel unit 12000, and an advertisement management server 13000.

The mobile terminal 11000 is a mobile communication terminal capable of wirelessly accessing a mobile communication system and immediately communicating with a desired counterparty ubiquitously, and records a plurality of operation applets, identified by applet identifier (AID) information, in an assigned memory area.

The mobile terminal 11000 operates in card mode in its initial stage, tags the panel unit 12000, searches for a record of designated applet identifier (AID) information from the plurality of recorded applet identifier (AID) information in response to a request from the panel unit 12000, and notifies the panel unit 12000 of search results once the record of designated AID information has been retrieved.

In the following description of the present invention, the mobile terminal 11000 will be described as recording a designated operation applet, and an applet corresponding to applet identifier (AID) information requested by the panel unit 12000 will be described as an operation applet capable of receiving advertisement media.

The fact that the mobile terminal 11000 has retrieved AID information designed by the panel unit 12000 means that the mobile terminal 11000 and the panel unit 12000 can activate the same operation applet and then perform data communication without suffering from errors.

The mobile terminal 11000 wakes up an operation applet corresponding to the designated applet identifier (AID) information, that is, an operation applet capable of receiving advertisements, so that it can enter an active state in response to a mode-switching request from the panel unit 12000, switches the operating mode from the initial card mode to read mode, and notifies the panel unit 12000 of the results of the wake-up and the mode-switching.

In this case, the mobile terminal 11000 additionally transmits a mode-switching request signal, requesting switching to card mode, to the panel unit 12000.

Furthermore, the mobile terminal 11000 receives advertisement media data from the panel unit 12000 while staying in a tagged state, and notifies the panel unit 12000 of the completion of the reception if the reception is completed without undergoing errors.

The panel unit 12000 includes a panel operation unit 12100 and an advertisement output unit 12200. The panel operation unit 12100 includes a process unit 12110, a tag applet unit 12120, an NFC controller unit 12130, and an advertisement signal processing unit 12140. The advertisement output unit 12200 includes an output unit 12220 and an antenna unit 12240.

When a mobile terminal 11000 tags the panel unit 12000 in initial read mode in which the information of a counterparty is read, the panel unit 12000 request a search for corresponding applet identifier (AID) information to check whether an operation applet for receiving an advertisement has been recorded in the mobile terminal 11000, and requests that the mobile terminal 11000 switches to read mode when receiving search results.

The process unit 12110 which constitutes a part of the panel operation unit 12100 of the panel unit 12000 requests a tag applet, including advertisement media, from the connected advertisement management server 13000, and receives the tag applet.

In the following description, a tag applet will be described as being matched to a corresponding advertising medium, and advertisement media will be described as multimedia including a still image(s), a moving image(s), a character(s), a sound(s), and/or an image(s), but not limited thereto.

The process unit 12110 records the received advertisement media and tag applet in respective assigned areas of the tag applet unit 12120. There are a variety of types of tag applets depending on the contents and purposes of advertisements, and the tag applet unit 12120 records tag applets which are matched to a plurality of various advertisement media.

Since the process unit 12110 performs control so that any advertisement media selected from among those recorded in the tag applet unit 12120 is applied and output to the advertisement signal processing unit 12140, the advertisement signal processing unit 12140 classifies the applied advertisement media as a multimedia signal including an image(s), a sound(s), or a character(s) and outputs the multimedia signal to the output unit 12220 of the advertisement output unit 12200.

The output unit 12220 includes a video unit for outputting video signals and character signals and an audio unit for outputting sound signals.

Meanwhile, the process unit 12110 performs control so that a tag applet matched to an advertisement medium output by the advertisement signal processing unit 12140 can be read from the tag applet unit 12120, and be applied to and output by the NFC controller unit 12130.

Since the NFC controller unit 12130 outputs the applied tag applet to the antenna unit 12240 of the advertisement output unit 12200, the antenna unit 12240 can radiate a signal which resonates with, for example, a radio frequency in the 13.56 MHz band.

In an embodiment, when the mobile terminal 11000 tags the antenna unit 12240, the antenna unit 12240 detects the tagging of the mobile terminal 11000 and provides notification to the NFC controller unit 12130 of the panel operation unit 12100, and the NFC controller unit 12130 requests a search for applet identifier (AID) information to check if the AID information of the operation applet which will receive an advertisement has been recorded in the mobile terminal and outputs a signal requesting the mode-switching of the mobile terminal 11000 if the corresponding AID information has been retrieved and returned.

The NFC controller unit 12130 checks if the mobile terminal 11000 has switched to read mode in response to a mode-switching request, and performs switching to card mode which provides recorded data when a signal requesting mode-switching is received from the mobile terminal 11000.

When the switching to card mode has been performed, the NFC controller unit 12130 searches for advertisement media, being currently output by the output unit 12220, from the tag applet unit 12120 and then outputs the advertisement media to the antenna unit 12240 under the control of the process unit 12110, and the antenna unit radiates data to the mobile terminal 11000.

Here, the output unit 12220 and the antenna unit 12240 may be paired with each other, and may output and radiate advertisement media of the same content under the control and monitoring of the process unit 12110.

Therefore, when the output unit 12220 and the antenna unit 12240 form a single pair in accordance with the embodiment, a plurality of advertisement media is output at different times. When output units 12220 and antenna units 12240 form a plurality of pairs in accordance with another embodiment, a plurality of advertisement media can be simultaneously output and provided via respective paths. The different configurations according to the embodiment of the panel unit 12000 will be described in detail below with reference to the accompanying drawing.

The advertisement management server 13000 may create and provide a plurality of advertisement media in real time or search for and provide one or more of a plurality of recorded advertisement media in response to a request from the panel unit 12000. The advertisement management server 13000 includes a control unit 13100, an advertisement radiation DB unit 13200, and a tag applet DB unit 13300. The configuration of the advertisement management server 13000 will be described in detail below with reference to the accompanying drawings.

FIG. 2 is a detailed functional block diagram illustrating the configuration of an advertisement management server 13000 according to an embodiment of the present invention.

Referring to FIG. 2, the advertisement management server 13000 will now be described in detail. The control unit 13100 controls and monitors the advertisement radiation DB unit 13200 and the tag applet DB unit 13300 so that created or retrieved advertisement media can be delivered in real time when a signal requesting the provision of a tag applet including selected advertisement media is received from the panel unit 12000.

When the advertisement radiation DB unit 13200 is controlled by the control unit 13100 so that the advertisement radiation DB unit 13200 generates advertisement media in real time, the advertisement radiation DB unit 13200 may receive a multimedia signal from the outside and then create a new advertisement medium in real time, may create a new advertisement medium using a multimedia signal received from the outside and an advertisement medium retrieved in real time, or may create a new advertisement medium using a plurality of retrieved advertisement media in real time.

The advertisement radiation DB unit 13200 may record the advertisement medium, created in real time, in its own assigned area, and search for and reuse it later.

Furthermore, under the control of the control unit 13100, the tag applet DB unit 13300 creates a tag applet, which matches the advertisement medium created by the advertisement radiation DB unit 13200, and at the same time transmits it to the advertisement radiation DB unit 13200 and records it in its own assigned area.

Here, the tag applet is described as being an application program which enables a counterparty to receive an advertisement medium which is created and radiated using an NFC wireless method.

The control unit 13100 controls the advertisement radiation DB unit 13200, so that a created or retrieved advertisement medium is read. The control unit 13100 controls the tag applet DB unit 13300 so that a tag applet which is matched to the advertisement medium is newly created or a corresponding retrieved tag applet is applied to the advertisement radiation DB unit 13200.

That is, according to an embodiment of the present invention, when the advertisement radiation DB unit 13200 creates a new advertisement medium, a new tag created by the tag applet DB unit 13300 is used. In contrast, when the advertisement radiation DB unit 13200 retrieves an existing recorded advertisement medium, an existing tag applet recorded in the tag applet DB unit 13300 is retrieved and used.

The advertisement radiation DB unit 13200 completes provision by transmitting the created and retrieved advertisement medium and the corresponding tag applet to the panel unit 12000 in real time under the control and monitoring of the control unit 13100.

FIG. 3 is a detailed functional block diagram illustrating the configuration of a panel unit 12000 according to a first embodiment of the present invention.

Referring to FIG. 3, the panel unit 12000 will now be described in detail. The panel unit 12000 according to the first embodiment includes a panel operation unit 12100, and an advertisement output unit 12200.

The panel operation unit 12100 includes a process unit 12110, a tag applet unit 12120, an NFC controller unit 12130, and an advertisement signal processing unit 12140. The advertisement output unit 12200 includes an output unit 12220, and an antenna unit 12240.

Here, the output unit 12220 and antenna unit 12240 of the advertisement output unit 12200 form a pair so that they output and radiate signals of the same content while operating in conjunction with each other.

That is, the output unit 12220 and the antenna unit 12240 which constitute the advertisement output unit 12200 output or radiate an advertisement medium of the same content, form a pair, and have corresponding paths over which data of the same content is transmitted.

The process unit 12110 which constitutes a part of the panel operation unit 12100 receives a corresponding tag applet matched to the advertisement media from the advertisement management server 13000, records it in the assigned area of the tag applet unit 12120, and applies it to the NFC controller unit 12130 and the advertisement signal processing unit 12140.

The NFC controller unit 12130 outputs a designated advertisement medium to the antenna unit 12240 via a corresponding path in the form of data under the control and monitoring of the process unit 12110.

Furthermore, the advertisement signal processing unit 12140 outputs a designated advertisement medium to the output unit 12220 via a corresponding path in the form of a multimedia signal under the control and monitoring of the process unit 12110.

The advertisement output unit 12200 outputs one or more designated advertisement media under the control of the panel operation unit 12100. It is apparent that when a plurality of advertisements are output, different advertisement media are output and radiated at different times.

In the configuration according to the first embodiment of the present invention, a selected advertisement medium is output through the output unit 12220 in the form of a multimedia signal, and, when the mobile terminal 11000 tags the antenna unit 12240, an advertisement medium of content which is the same as the content of the advertisement medium output through the output unit 12220 is provided in the form of data.

Accordingly, the mobile terminal 11000 receives the advertisement medium, which output through the output unit 12220, in the form of data by tagging the antenna unit 12240 and then records it in its own memory area, so that there are the advantages of repeatedly viewing and/or listening to the corresponding advertisement medium ubiquitously and analyzing it over time.

In particular, there is the advantage of reviewing or comparing and analyzing the content of the advertisement media (or media) when the content of an advertisement is summarized or the time tables of a movie or the prices of a product are compared with each other.

FIG. 4 is a detailed functional block diagram illustrating the configuration of a panel unit 12000 according to a second embodiment of the present invention.

Referring to FIG. 4, the panel unit 12000 will now be described in detail. The panel unit 12000 according to the second embodiment includes a panel operation unit 12100, and an advertisement output unit 12200.

The panel operation unit 12100 includes a process unit 12110, a tag applet unit 12120, an NFC controller unit 12130, and an advertisement signal processing unit 12140.

In an embodiment, the first output unit 12221 and the first antenna unit 12241 form a pair, the second output unit 12222 and the second antenna unit 12242 form a pair, . . . , and the n-th output unit 12223 and the n-th antenna unit 12243 form a pair.

The output unit 12220 and the antenna unit 12240 paired as described above output an advertisement medium of the same content via a corresponding path of each pair.

Since the process unit 12110 and tag applet unit 12120 of the panel operation unit 12100 are the same as those of the first embodiment, a description thereof is omitted to avoid a redundant description.

The NFC controller unit 12130 may separately manage the paths of the plurality of antenna units 12241, 12242, . . . , and 12243 which constitute the antenna unit 12240, and performs control so that the plurality of antenna units 12241, 12242, . . . , and 12243 output and radiate corresponding tag applets and so that when it is determined that the mobile terminal 11000 has performed tagging or tag reading on one of the antenna units 12241, 12242, . . . , and 12243, a matched corresponding advertisement medium is output in the form of data, thus being radiated via the corresponding antenna unit 12241, 12242 . . . , or 12243.

Furthermore, the advertisement signal processing unit 12140 may separately manage the paths of the plurality of output units 12221, 12222 . . . , and 12223 which constitute the output unit 12220, and performs control so that a corresponding advertisement medium is output in the form of a multimedia signal.

Here, the NFC controller unit 12130 and the advertisement signal processing unit 12140 are synchronized with each other and output information corresponding to an advertisement medium of the same content over a path to which a pair of the synchronized output unit 12220 and antenna unit 12240 of the advertisement output unit 12200 are connected.

The configuration of the embodiment of the present invention has the advantage of selectively or simultaneously outputting one or more advertisements selected from among a plurality of a variety of advertisements using a single advertisement medium.

FIG. 5 is a flowchart illustrating a process of operating the advertisement information provision system according to an embodiment of the present invention.

Referring to FIG. 5, the process of operating the advertisement information provision system according to the embodiment of the present invention will now be described in detail. The mobile terminal operates in card mode in its initial stage, the panel unit operates in read mode in its initial stage, and the panel unit outputs an advertisement medium in the form of a multimedia signal and also outputs a tag applet matched to the advertisement medium in the form of data in accordance with the first or second embodiment.

Card mode is described as being the state of providing recorded information to a counterparty, while read mode is described as being the state of reading the information of a counterparty.

When a user desires to download the content of an advertisement medium currently being advertised in order to repeatedly play back or analyze the content of the advertisement medium output by an output unit of the panel unit, the mobile terminal tags a corresponding antenna unit which is paired with the output unit at step S2010.

The panel unit issues a request to the mobile terminal that it search for corresponding applet identifier (AID) and make a response at step S2020 in order to check whether a corresponding operation applet capable of receiving the advertisement medium has been recorded in the mobile terminal.

The mobile terminal searches for the corresponding AID information and then returns information about retrieved corresponding ID in response to the request from the panel unit at step S2030. In this case, the panel unit requests mode-switching from the mobile terminal at step S2040. The request for mode-switching is to request that the mobile terminal switches to read mode and operates in read mode.

When the mobile terminal receives a mode-switching request signal from the panel unit, the mobile terminal wakes up a corresponding operation applet so that it is activated to receive the advertisement medium at step S2050, and is automatically switched from the current card mode to read mode at step S2060.

That is, the mobile terminal automatically switches from current card mode to read mode, and at the same time notifies the panel unit of the mode-switching and requests that the panel unit automatically switch its operating mode from read mode to card mode at step S2070.

The panel unit switches the current operating mode of the mobile terminal from read mode back to card mode in response to the response and the request at step S2080, and returns the results of the automatic mode-switching to the card mode to the mobile terminal at step S2090.

Furthermore, the panel unit requests to the advertisement management server a tag applet capable of downloading an advertisement medium matched to the tagged antenna unit and the corresponding advertisement medium from the advertisement management server at step S2100, and the advertisement management server creates or searches for the requested advertisement medium and the matched tag applet in real time at step S2110, and transmits and provides the advertisement medium retrieved or created in real time to the panel unit at step S2120.

The panel unit checks the advertisement medium and the matched tag applet for errors while receiving the advertisement medium and the matched tag applet provided by the advertisement management server, records the received advertisement medium and matched tag applet in the assigned memory area of the tag applet unit if they have been received without any error, and monitors whether the mobile terminal performs tagging for reading at step S2130.

In this case, if the corresponding advertisement medium and matched tag applet have been already recorded in the memory area of the tag applet unit, the panel unit may not request transmission from the advertisement management server.

When the panel determines that the mobile terminal is in a tag reading state so that it can read the advertisement medium in the form of data at step S2140, the panel unit transmits the matched tag applet and the corresponding advertisement medium to the mobile terminal via the tagged corresponding antenna unit in the form of data at step S2150.

The mobile terminal checks whether the data of the advertisement medium has been received without any error using the received tag applet at step S2160, and, if the overall data of the advertisement medium has been received without any error, the mobile terminal returns a reception completion signal to the panel unit at step S2170.

Here, according to an embodiment of the present invention, it may be checked whether such an optical code has been accurately scanned or captured by the camera unit 1110, using the output unit 2120.

According to an embodiment of the present invention, the NFC antenna unit 1130 is configured to be turned to a wireless frequency in the 13.56 MHz band, and wirelessly transmits and receives NFC signals.

The QR analysis unit 1210 receives the optical code captured by the camera unit 1110, recognizes and analyzes a QR code, and converts the QR code into commodity data.

The commodity data recognized, analyzed and obtained using the QR code includes a variety of information such as the name, manufacturer, management number, release date, expiration date, price, features, use and advertisement information of a commodity 1400, and may further include link information.

The process unit 1220 monitors and controls the functional units of the panel unit 1100 and the operation unit 1200, receives the commodity data from the QR analysis unit 1210, and outputs the commodity data to the server unit 1300.

Furthermore, the process unit 1220 receives a tag applet provided by the server unit 1300, and applies the tag applet to the NFC controller unit 1230.

The NFC controller unit 1230 operates in NFC read mode in its initial stage, and records information about the tag applet, provided by the process unit 1220, in the assigned area of the tag applet recording unit 1240.

The NFC controller unit 1230 monitors the NFC antenna unit 1130 of the panel unit 1100, and detects the tagging of the NFC mobile terminal 1500.

When the NFC controller unit 1230 detects the tagging of the NFC mobile terminal 1500, it requests applet identifier (AID), requests that mode-switching is automatically performed, and receives a response signal indicative of corresponding results.

Once the NFC controller unit 1230 has received the response signal, it is automatically switched from read mode to card mode, and outputs a tag applet recorded in the tag applet recording unit 1240, thereby transmitting the tag applet to the NFC mobile terminal 1500 via the NFC antenna unit 1130.

In this case, when the NFC controller unit 1230 receives a response indicative of the normal reception of the tag applet without transmission error from the NFC mobile terminal 1500, it deletes the corresponding tag applet recorded in the tag applet recording unit 1240. That is, the information of the tag applet is allowed to be provided only once.

The server unit 1300 includes the tag applet issuance unit 1310, receives the commodity data provided by the operation unit 1200, converts the commodity data into a tag applet using the tag applet issuance unit 1310, and transmits the tag applet to the operation unit 1200.

The NFC mobile terminal 1500 connects to the mobile communication system, and communicates with a desired counterparty via a wireless connection. The NFC mobile terminal 1500 may include an NFC communication function and then perform NFC communications. Alternatively, the NFC mobile terminal 1500 may include only an NFC communication function.

The NFC mobile terminal 1500 includes a plurality of application applets including a driving applet, and these applets are identified by respective pieces of AID information. The driving applet is described as being an application program which transmits and receives commodity information.

The NFC mobile terminal 1500 operates in card mode in its initial stage, receives a signal requesting AID information and a signal requesting mode-switching from the operation unit 1200 via the panel unit 1100, provides retrieved AID information, wakes up and operates a corresponding driving applet, performs switching to read mode, and returns a response signal indicative of results corresponding to a request signal to the operation unit 1200 via the panel unit 1100.

After the NFC mobile terminal 1500 has been automatically switched to read mode, the NFC mobile terminal 1500 receives a tag applet from the operation unit 1200, and outputs the tag applet via its own output unit using an operating driving applet in the form of multimedia.

The configuration according to the fifth embodiment of the present invention converts commodity information recorded in a QR code or an optical code represented on the surface of a commodity into a tag applet and transfers the tag applet to the NFC mobile terminal, and the NFC mobile terminal receives the tag applet using an NFC method and outputs the commodity information using a waked driving applet in the form of multimedia content.

FIG. 11 is a functional block diagram illustrating the configuration of a commodity information provision system according to a sixth embodiment of the present invention.

Referring to FIG. 11, the commodity information provision system 2000 according to the sixth embodiment of the present invention will now be described in detail. The commodity information provision system 2000 according to the sixth embodiment of the present invention includes an apparatus unit 2090 including a panel unit 2100 and operation unit 2200 and a server unit 2300.

The commodity information provision system 2000 according to the sixth embodiment is the same as the commodity information provision system 1000 of the fifth embodiment except that the commodity information provision system 2000 according to the sixth embodiment further includes a barcode scanner unit 2140 and a barcode analysis unit 2250 compared to the commodity information provision system 1000 of the fifth embodiment.

That is, since the configuration of the server unit 2300 including an output unit 2120, an NFC antenna unit 2130, a process unit 2220, an NFC controller unit 2230, a tag applet recording unit 2240, and a tag applet issuance unit 2310 is the same as that of the fifth embodiment except for reference numerals, redundant descriptions will be omitted and only necessary descriptions will be given.

Therefore, the configurations of the unique barcode scanner unit 2140 and barcode analysis unit 2250 will now be described in detail.

The camera unit 2110 captures a QR code, and applies the QR code to both the output unit 2120 and the QR analysis unit 2210. The barcode scanner unit 2140 scans a barcode, and applies the scanned image to both the output unit 2120 and the barcode analysis unit 2250.

The barcode and the QR code may be the same in the type and content of information to be recorded, and may be different in the amount of information which can be recorded therein.

That is, the barcode is a computer-readable 1D code, and can record a relatively limited amount of information because the amount of data which can be recorded in the barcode is small. The QR code is a computer-readable 2D code, and is widely used recently QR because it has the advantages of being able to record a maximum of 23,648 bits and also recording link information.

The configuration according to the sixth embodiment of the present invention converts commodity information recorded in optical codes including a barcode and a QR code represented on the surface of a commodity 1400 into a tag applet and transfers the tag applet to the NFC mobile terminal 1500, and the NFC mobile terminal 1500 receives the tag applet using an NFC method and outputs the commodity information using a waked driving applet in the form of multimedia content. The configuration according to the sixth embodiment is different from the configuration of the present invention in that the configuration according to the sixth embodiment uses both the barcode and the QR code.
